I can think of 2 things, though it may not work.
1) Wrap heat tape around the pipes and then insulate them.
2)Build a box around both pipes and fill it with insulation?
I've seen a couple house trailers that are set up like 1 and have been like that for years. I don't know what to do about the faucet ends or the first couple feet in the ground...
